Device, method, and graphical user interface for configuring and implementing restricted interactions with a user interface

ABSTRACT

An electronic device, while in a restricted interaction mode in an application other than a call application, displays a first user interface that includes a plurality of user interface objects, and receives an incoming call. The electronic device determines whether the incoming phone call satisfies predefined signaling criteria. In accordance with a determination that the incoming call satisfies the predefined signaling criteria, the electronic device outputs a signal that indicates the incoming call. In accordance with a determination that the incoming phone call does not satisfy the predefined criteria, the electronic device foregoes outputting the signal indicating the incoming call.

TECHNICAL FIELD

This relates generally to electronic devices with touch-sensitive surfaces, including but not limited to electronic devices with touch-sensitive surfaces that display user interfaces with user interface objects.

BACKGROUND

The use of touch-sensitive surfaces as input devices for computers and other electronic computing devices has increased significantly in recent years. Exemplary touch-sensitive surfaces include touch pads and touch screen displays. Such surfaces are widely used to manipulate user interface objects on a display.

At times, it may be desirable to restrict interactions with the user interface of an electronic device. For example, a parent or teacher may want to disable certain icons on a touch screen, hardware buttons, sensors, and/or other parts of the user interface so that a young child can use a particular application on the device without accidentally accessing other applications and system functions or deleting files. Similarly, a caregiver for a person with a cognitive impairment (e.g., autism) may want to restrict interaction with the device by disabling and/or hiding certain icons on a touch screen, hardware buttons, sensors, and/or other parts of the user interface that would distract the person with the cognitive impairment from the task at hand. As another example, a person may want to configure the device for a kiosk mode that restricts access to applications and system functions on the device.

But existing methods for configuring a user interface for restricted interaction are cumbersome and inefficient. A user typically has to navigate through multiple menus and/or screens to configure the restrictions. In addition, existing methods take longer than necessary to configure the device, thereby wasting energy. This latter consideration is particularly important in battery-operated devices.

In addition, while in a restricted interaction mode, the device typically does not inform users of incoming voice or video calls, which may cause a user (e.g., a parent, caregiver, or even a child) to miss an important call. This problem also needs to be addressed.

SUMMARY

Accordingly, there is a need for electronic devices with faster, more efficient methods and interfaces for configuring restricted interaction with their user interfaces. Such methods and interfaces may complement or replace conventional methods for configuring restricted interactions. Such methods and interfaces reduce the cognitive burden on a user while configuring the device and produce a more efficient human-machine interface. For battery-operated devices, such methods and interfaces conserve power and increase the time between battery charges.

In addition, there is a need for electronic devices with methods and interfaces for signaling to a user, while the device is in a restricted interaction mode, that there is an important incoming call.

The above deficiencies and other problems associated with user interfaces for electronic devices with touch-sensitive surfaces are reduced or eliminated by the disclosed devices.

DESCRIPTION OF EMBODIMENTS

At times, it may be desirable to restrict interactions with the user interface of an electronic device. Certain icons on a touch screen, hardware buttons, sensors, and/or other parts of the user interface may need to be disabled. But existing methods for configuring a user interface for restricted interaction are cumbersome and inefficient. In the embodiments described below, an improved method for configuring a user interface for restricted interaction is achieved by displaying the user interface in an interaction configuration mode, where one or more user interface objects can be selected for deactivation based on one or more simple touch inputs. In addition, other parts of the user interface, such as responses to device rotation, shaking, and motion, can also be disabled. While in a restricted interaction mode, the one or more user interface objects selected in the interaction configuration mode are deactivated (e.g., disabled or otherwise prevented from being activated) so that the user cannot interact with the deactivated user interface objects. This method provides an efficient, intuitive process for configuring restricted interaction with a user interface, thereby eliminating the need for extra, separate steps to configure the user interface.

In addition, while in the restricted interaction mode, the device typically does not inform users of incoming voice or video calls, which may cause a user (e.g., a parent, caregiver, or even a child) to miss an important call. This problem can be solved by having the electronic device alert a user to incoming calls that meet predefined signaling criteria. For example, the device provides an audible and/or visual signal if the call is coming from a number on a predefined “whitelist.” Alternatively, if multiple calls are received from the same number in a predefined time period (which indicates an urgent call), the device provides an audible and/or visual signal that there is an incoming call.

FIGS. 6A-6E are flow diagrams illustrating a method of configuring restricted interaction with a user interface. FIG. 8 is a flow diagram illustrating a method of signaling an incoming call in a restricted interaction mode. The user interfaces in FIGS. 5A-5AD are used to illustrate the processes in FIGS. 6A-6E and FIG. 8.

Exemplary Devices

Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to one of ordinary skill in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits, and networks have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.

It will also be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first user interface could be termed a second user interface, and, similarly, a second user interface could be termed a first user interface, without departing from the scope of the present invention. The first user interface and the second user interface are both user interfaces, but they are not the same user interface.

The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the description of the invention and the appended claims, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

As used herein, the term “if” may be construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” may be construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context.

Embodiments of electronic devices, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the device is a portable communications device, such as a mobile telephone, that also contains other functions, such as PDA and/or music player functions. Exemplary embodiments of portable multifunction devices include, without limitation, the iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, Calif. Other portable electronic devices, such as laptops or tablet computers with touch-sensitive surfaces (e.g., touch screen displays and/or touch pads), may also be used. It should also be understood that, in some embodiments, the device is not a portable communications device, but is a desktop computer with a touch-sensitive surface (e.g., a touch screen display and/or a touch pad).

In the discussion that follows, an electronic device that includes a display and a touch-sensitive surface is described. It should be understood, however, that the electronic device may include one or more other physical user-interface devices, such as a physical keyboard, a mouse and/or a joystick.

The device typically supports a variety of applications, such as one or more of the following: a drawing application, a presentation application, a word processing application, a website creation application, a disk authoring application, a spreadsheet application, a gaming application, a telephone application, a video conferencing application, an e-mail application, an instant messaging application, a workout support application, a photo management application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and/or a digital video player application.

The various applications that may be executed on the device may use at least one common physical user-interface device, such as the touch-sensitive surface. One or more functions of the touch-sensitive surface as well as corresponding information displayed on the device may be adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch-sensitive surface) of the device may support the variety of applications with user interfaces that are intuitive and transparent to the user.

The visual output may include graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output may correspond to user-interface objects.

Touch screen 112 has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch screen 112 and display controller 156 (along with any associated modules and/or sets of instructions in memory 102) detect contact (and any movement or breaking of the contact) on touch screen 112 and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on touch screen 112. In an exemplary embodiment, a point of contact between touch screen 112 and the user corresponds to a finger of the user.

Touch screen 112 may use LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies may be used in other embodiments. Touch screen 112 and display controller 156 may detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch screen 112. In an exemplary embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone®, iPod Touch®, and iPad® from Apple Inc. of Cupertino, Calif.

Touch screen 112 may have a video resolution in excess of 100 dpi. In some embodiments, the touch screen has a video resolution of approximately 160 dpi. The user may make contact with touch screen 112 using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.

In some embodiments, in addition to the touch screen, device 100 may include a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad may be a touch-sensitive surface that is separate from touch screen 112 or an extension of the touch-sensitive surface formed by the touch screen.

Device 100 also includes power system 162 for powering the various components. Power system 162 may include a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.

Device 100 may also include one or more optical sensors 164. FIG. 1A shows an optical sensor coupled to optical sensor controller 158 in I/O subsystem 106. Optical sensor 164 may include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor 164 receives light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with imaging module 143 (also called a camera module), optical sensor 164 may capture still images or video. In some embodiments, an optical sensor is located on the back of device 100, opposite touch screen display 112 on the front of the device, so that the touch screen display may be used as a viewfinder for still and/or video image acquisition. In some embodiments, another optical sensor is located on the front of the device so that the user's image may be obtained for videoconferencing while the user views the other video conference participants on the touch screen display.

Device 100 may also include one or more proximity sensors 166. FIG. 1A shows proximity sensor 166 coupled to peripherals interface 118. Alternately, proximity sensor 166 may be coupled to input controller 160 in I/O subsystem 106. In some embodiments, the proximity sensor turns off and disables touch screen 112 when the multifunction device is placed near the user's ear (e.g., when the user is making a phone call).

Device 100 may also include one or more accelerometers 168. FIG. 1A shows accelerometer 168 coupled to peripherals interface 118. Alternately, accelerometer 168 may be coupled to an input controller 160 in I/O subsystem 106. In some embodiments, information is displayed on the touch screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers. Device 100 optionally includes, in addition to accelerometer(s) 168, a magnetometer (not shown) and a GPS (or GLONASS or other global navigation system) receiver (not shown) for obtaining information concerning the location and orientation (e.g., portrait or landscape) of device 100.

In some embodiments, the software components stored in memory 102 include operating system 126, communication module (or set of instructions) 128, contact/motion module (or set of instructions) 130, graphics module (or set of instructions) 132, text input module (or set of instructions) 134, Global Positioning System (GPS) module (or set of instructions) 135, and applications (or sets of instructions) 136. Furthermore, in some embodiments, memory 102 stores device/global internal state 157, as shown in FIGS. 1A and 3. Device/global internal state 157 includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch screen display 112; sensor state, including information obtained from the device's various sensors and input control devices 116; and location information concerning the device's location and/or attitude. In some embodiments, memory 102 also stores one or more individual profiles 159, where each individual profile includes information identifying user interface objects, of a particular user interface or one or more user interfaces of a particular application or widget, that are accessible to a respective user.

Operating system 126 (e.g., Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.

Communication module 128 facilitates communication with other devices over one or more external ports 124 and also includes various software components for handling data received by RF circuitry 108 and/or external port 124. External port 124 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with the 30-pin connector used on iPod (trademark of Apple Inc.) devices.

Contact/motion module 130 may detect contact with touch screen 112 (in conjunction with display controller 156) and other touch sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module 130 includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module 130 receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, may include determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations may be applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module 130 and display controller 156 detect contact on a touchpad.

Contact/motion module 130 may detect a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns. Thus, a gesture may be detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (lift off) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (lift off) event.

Graphics module 132 includes various known software components for rendering and displaying graphics on touch screen 112 or other display, including components for changing the intensity of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including without limitation text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations and the like.

In some embodiments, graphics module 132 stores data representing graphics to be used. Each graphic may be assigned a corresponding code. Graphics module 132 receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to display controller 156.

Text input module 134, which may be a component of graphics module 132, provides soft keyboards for entering text in various applications (e.g., contacts 137, e-mail 140, IM 141, browser 147, and any other application that needs text input).

GPS module 135 determines the location of the device and provides this information for use in various applications (e.g., to telephone 138 for use in location-based dialing, to camera 143 as picture/video metadata, and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets).

Each of the above identified modules and applications correspond to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules may be combined or otherwise re-arranged in various embodiments. In some embodiments, memory 102 may store a subset of the modules and data structures identified above. Furthermore, memory 102 may store additional modules and data structures not described above.

In some embodiments, device 100 is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen and/or a touchpad. By using a touch screen and/or a touchpad as the primary input control device for operation of device 100, the number of physical input control devices (such as push buttons, dials, and the like) on device 100 may be reduced.

The predefined set of functions that may be performed exclusively through a touch screen and/or a touchpad include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates device 100 to a main, home, or root menu from any user interface that may be displayed on device 100. In such embodiments, the touchpad may be referred to as a “menu button.” In some other embodiments, the menu button may be a physical push button or other physical input control device instead of a touchpad.

FIG. 1B is a block diagram illustrating exemplary components for event handling in accordance with some embodiments. In some embodiments, memory 102 (in FIG. 1A) or 370 (FIG. 3) includes event sorter 170 (e.g., in operating system 126) and a respective application 136-1 (e.g., any of the aforementioned applications 137-151, 155, 380-390).

Event sorter 170 receives event information and determines the application 136-1 and application view 191 of application 136-1 to which to deliver the event information. Event sorter 170 includes event monitor 171 and event dispatcher module 174. In some embodiments, application 136-1 includes application internal state 192, which indicates the current application view(s) displayed on touch sensitive display 112 when the application is active or executing. In some embodiments, device/global internal state 157 is used by event sorter 170 to determine which application(s) is (are) currently active, and application internal state 192 is used by event sorter 170 to determine application views 191 to which to deliver event information.

In some embodiments, application internal state 192 includes additional information, such as one or more of: resume information to be used when application 136-1 resumes execution, user interface state information that indicates information being displayed or that is ready for display by application 136-1, a state queue for enabling the user to go back to a prior state or view of application 136-1, and a redo/undo queue of previous actions taken by the user.

Event monitor 171 receives event information from peripherals interface 118. Event information includes information about a sub-event (e.g., a user touch on touch-sensitive display 112, as part of a multi-touch gesture). Peripherals interface 118 transmits information it receives from I/O subsystem 106 or a sensor, such as proximity sensor 166, accelerometer(s) 168, and/or microphone 113 (through audio circuitry 110). Information that peripherals interface 118 receives from I/O subsystem 106 includes information from touch-sensitive display 112 or a touch-sensitive surface.

In some embodiments, event monitor 171 sends requests to the peripherals interface 118 at predetermined intervals. In response, peripherals interface 118 transmits event information. In other embodiments, peripheral interface 118 transmits event information only when there is a significant event (e.g., receiving an input above a predetermined noise threshold and/or for more than a predetermined duration).

In some embodiments, event sorter 170 also includes a hit view determination module 172 and/or an active event recognizer determination module 173.

Hit view determination module 172 provides software procedures for determining where a sub-event has taken place within one or more views, when touch sensitive display 112 displays more than one view. Views are made up of controls and other elements that a user can see on the display.

Another aspect of the user interface associated with an application is a set of views, sometimes herein called application views or user interface windows, in which information is displayed and touch-based gestures occur. The application views (of a respective application) in which a touch is detected may correspond to programmatic levels within a programmatic or view hierarchy of the application. For example, the lowest level view in which a touch is detected may be called the hit view, and the set of events that are recognized as proper inputs may be determined based, at least in part, on the hit view of the initial touch that begins a touch-based gesture.

Hit view determination module 172 receives information related to sub-events of a touch-based gesture. When an application has multiple views organized in a hierarchy, hit view determination module 172 identifies a hit view as the lowest view in the hierarchy which should handle the sub-event. In most circumstances, the hit view is the lowest level view in which an initiating sub-event occurs (i.e., the first sub-event in the sequence of sub-events that form an event or potential event). Once the hit view is identified by the hit view determination module, the hit view typically receives all sub-events related to the same touch or input source for which it was identified as the hit view.

Active event recognizer determination module 173 determines which view or views within a view hierarchy should receive a particular sequence of sub-events. In some embodiments, active event recognizer determination module 173 determines that only the hit view should receive a particular sequence of sub-events. In other embodiments, active event recognizer determination module 173 determines that all views that include the physical location of a sub-event are actively involved views, and therefore determines that all actively involved views should receive a particular sequence of sub-events. In other embodiments, even if touch sub-events were entirely confined to the area associated with one particular view, views higher in the hierarchy would still remain as actively involved views.

Event dispatcher module 174 dispatches the event information to an event recognizer (e.g., event recognizer 180). In embodiments including active event recognizer determination module 173, event dispatcher module 174 delivers the event information to an event recognizer determined by active event recognizer determination module 173. In some embodiments, event dispatcher module 174 stores in an event queue the event information, which is retrieved by a respective event receiver module 182.

In some embodiments, operating system 126 includes event sorter 170. Alternatively, application 136-1 includes event sorter 170. In yet other embodiments, event sorter 170 is a stand-alone module, or a part of another module stored in memory 102, such as contact/motion module 130.

In some embodiments, application 136-1 includes a plurality of event handlers 190 and one or more application views 191, each of which includes instructions for handling touch events that occur within a respective view of the application's user interface. Each application view 191 of the application 136-1 includes one or more event recognizers 180. Typically, a respective application view 191 includes a plurality of event recognizers 180. In other embodiments, one or more of event recognizers 180 are part of a separate module, such as a user interface kit (not shown) or a higher level object from which application 136-1 inherits methods and other properties. In some embodiments, a respective event handler 190 includes one or more of: data updater 176, object updater 177, GUI updater 178, and/or event data 179 received from event sorter 170. Event handler 190 may utilize or call data updater 176, object updater 177 or GUI updater 178 to update the application internal state 192. Alternatively, one or more of the application views 191 includes one or more respective event handlers 190. Also, in some embodiments, one or more of data updater 176, object updater 177, and GUI updater 178 are included in a respective application view 191.

A respective event recognizer 180 receives event information (e.g., event data 179) from event sorter 170, and identifies an event from the event information. Event recognizer 180 includes event receiver 182 and event comparator 184. In some embodiments, event recognizer 180 also includes at least a subset of: metadata 183, and event delivery instructions 188 (which may include sub-event delivery instructions).

Event receiver 182 receives event information from event sorter 170. The event information includes information about a sub-event, for example, a touch or a touch movement. Depending on the sub-event, the event information also includes additional information, such as location of the sub-event. When the sub-event concerns motion of a touch the event information may also include speed and direction of the sub-event. In some embodiments, events include rotation of the device from one orientation to another (e.g., from a portrait orientation to a landscape orientation, or vice versa), and the event information includes corresponding information about the current orientation (also called device attitude) of the device.

Event comparator 184 compares the event information to predefined event or sub-event definitions and, based on the comparison, determines an event or sub-event, or determines or updates the state of an event or sub-event. In some embodiments, event comparator 184 includes event definitions 186. Event definitions 186 contain definitions of events (e.g., predefined sequences of sub-events), for example, event 1 (187-1), event 2 (187-2), and others. In some embodiments, sub-events in an event 187 include, for example, touch begin, touch end, touch movement, touch cancellation, and multiple touching. In one example, the definition for event 1 (187-1) is a double tap on a displayed object. The double tap, for example, comprises a first touch (touch begin) on the displayed object for a predetermined phase, a first lift-off (touch end) for a predetermined phase, a second touch (touch begin) on the displayed object for a predetermined phase, and a second lift-off (touch end) for a predetermined phase. In another example, the definition for event 2 (187-2) is a dragging on a displayed object. The dragging, for example, comprises a touch (or contact) on the displayed object for a predetermined phase, a movement of the touch across touch-sensitive display 112, and lift-off of the touch (touch end). In some embodiments, the event also includes information for one or more associated event handlers 190.

In some embodiments, event definition 187 includes a definition of an event for a respective user-interface object. In some embodiments, event comparator 184 performs a hit test to determine which user-interface object is associated with a sub-event. For example, in an application view in which three user-interface objects are displayed on touch-sensitive display 112, when a touch is detected on touch-sensitive display 112, event comparator 184 performs a hit test to determine which of the three user-interface objects is associated with the touch (sub-event). If each displayed object is associated with a respective event handler 190, the event comparator uses the result of the hit test to determine which event handler 190 should be activated. For example, event comparator 184 selects an event handler associated with the sub-event and the object triggering the hit test.

In some embodiments, the definition for a respective event 187 also includes delayed actions that delay delivery of the event information until after it has been determined whether the sequence of sub-events does or does not correspond to the event recognizer's event type.

When a respective event recognizer 180 determines that the series of sub-events do not match any of the events in event definitions 186, the respective event recognizer 180 enters an event impossible, event failed, or event ended state, after which it disregards subsequent sub-events of the touch-based gesture. In this situation, other event recognizers, if any, that remain active for the hit view continue to track and process sub-events of an ongoing touch-based gesture.

In some embodiments, a respective event recognizer 180 includes metadata 183 with configurable properties, flags, and/or lists that indicate how the event delivery system should perform sub-event delivery to actively involved event recognizers. In some embodiments, metadata 183 includes configurable properties, flags, and/or lists that indicate how event recognizers may interact with one another. In some embodiments, metadata 183 includes configurable properties, flags, and/or lists that indicate whether sub-events are delivered to varying levels in the view or programmatic hierarchy.

In some embodiments, a respective event recognizer 180 activates event handler 190 associated with an event when one or more particular sub-events of an event are recognized. In some embodiments, a respective event recognizer 180 delivers event information associated with the event to event handler 190. Activating an event handler 190 is distinct from sending (and deferred sending) sub-events to a respective hit view. In some embodiments, event recognizer 180 throws a flag associated with the recognized event, and event handler 190 associated with the flag catches the flag and performs a predefined process.

In some embodiments, event delivery instructions 188 include sub-event delivery instructions that deliver event information about a sub-event without activating an event handler. Instead, the sub-event delivery instructions deliver event information to event handlers associated with the series of sub-events or to actively involved views. Event handlers associated with the series of sub-events or with actively involved views receive the event information and perform a predetermined process.

In some embodiments, data updater 176 creates and updates data used in application 136-1. For example, data updater 176 updates the telephone number used in contacts module 137, or stores a video file used in video player module 145. In some embodiments, object updater 177 creates and updates objects used in application 136-1. For example, object updater 176 creates a new user-interface object or updates the position of a user-interface object. GUI updater 178 updates the GUI. For example, GUI updater 178 prepares display information and sends it to graphics module 132 for display on a touch-sensitive display.

In some embodiments, event handler(s) 190 includes or has access to data updater 176, object updater 177, and GUI updater 178. In some embodiments, data updater 176, object updater 177, and GUI updater 178 are included in a single module of a respective application 136-1 or application view 191. In other embodiments, they are included in two or more software modules.

It shall be understood that the foregoing discussion regarding event handling of user touches on touch-sensitive displays also applies to other forms of user inputs to operate multifunction devices 100 with input-devices, not all of which are initiated on touch screens, e.g., coordinating mouse movement and mouse button presses with or without single or multiple keyboard presses or holds, user movements taps, drags, scrolls, etc., on touch-pads, pen stylus inputs, movement of the device, oral instructions, detected eye movements, biometric inputs, and/or any combination thereof, which may be utilized as inputs corresponding to sub-events which define an event to be recognized.

FIG. 2 illustrates a portable multifunction device 100 having a touch screen 112 in accordance with some embodiments. The touch screen may display one or more graphics within user interface (UI) 200. In this embodiment, as well as others described below, a user may select one or more of the graphics by making a gesture on the graphics, for example, with one or more fingers 202 (not drawn to scale in the figure) or one or more styluses 203 (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the gesture may include one or more taps, one or more swipes (from left to right, right to left, upward and/or downward) and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with device 100. In some embodiments, inadvertent contact with a graphic may not select the graphic. For example, a swipe gesture that sweeps over an application icon may not select the corresponding application when the gesture corresponding to selection is a tap.

Device 100 may also include one or more physical buttons, such as “home” or menu button 204. As described previously, menu button 204 may be used to navigate to any application 136 in a set of applications that may be executed on device 100. Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI displayed on touch screen 112.

In one embodiment, device 100 includes touch screen 112, menu button 204, push button 206 for powering the device on/off and locking the device, volume adjustment button(s) 208, Subscriber Identity Module (SIM) card slot 210, head set jack 212, and docking/charging external port 124. Push button 206 may be used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval; to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In an alternative embodiment, device 100 also may accept verbal input for activation or deactivation of some functions through microphone 113.

FIG. 3 is a block diagram of an exemplary multifunction device with a display and a touch-sensitive surface in accordance with some embodiments. Device 300 need not be portable. In some embodiments, device 300 is a laptop computer, a desktop computer, a tablet computer, a multimedia player device, a navigation device, an educational device (such as a child's learning toy), a gaming system, or a control device (e.g., a home or industrial controller). Device 300 typically includes one or more processing units (CPU's) 310, one or more network or other communications interfaces 360, memory 370, and one or more communication buses 320 for interconnecting these components. Communication buses 320 may include circuitry (sometimes called a chipset) that interconnects and controls communications between system components. Device 300 includes input/output (I/O) interface 330 comprising display 340, which is typically a touch screen display. I/O interface 330 also may include a keyboard and/or mouse (or other pointing device) 350 and touchpad 355. Memory 370 includes high-speed random access memory, such as DRAM, SRAM, DDR RAM or other random access solid state memory devices; and may include non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid state storage devices. Memory 370 may optionally include one or more storage devices remotely located from CPU(s) 310. In some embodiments, memory 370 stores programs, modules, and data structures analogous to the programs, modules, and data structures stored in memory 102 of portable multifunction device 100 (FIG. 1), or a subset thereof. Furthermore, memory 370 may store additional programs, modules, and data structures not present in memory 102 of portable multifunction device 100. For example, memory 370 of device 300 may store drawing module 380, presentation module 382, word processing module 384, website creation module 386, disk authoring module 388, and/or spreadsheet module 390, while memory 102 of portable multifunction device 100 (FIG. 1) may not store these modules.

Each of the above identified elements in FIG. 3 may be stored in one or more of the previously mentioned memory devices. Each of the above identified modules corresponds to a set of instructions for performing a function described above. The above identified modules or programs (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules may be combined or otherwise re-arranged in various embodiments. In some embodiments, memory 370 may store a subset of the modules and data structures identified above. Furthermore, memory 370 may store additional modules and data structures not described above.

Attention is now directed towards embodiments of user interfaces (“UI”) that may be implemented on portable multifunction device 100.

FIG. 4A illustrates an exemplary user interface for a menu of applications on portable multifunction device 100 in accordance with some embodiments. Similar user interfaces may be implemented on device 300. In some embodiments, user interface 400 includes the following elements, or a subset or superset thereof:

-   -   Signal strength indicator(s) 402 for wireless communication(s),         such as cellular and Wi-Fi signals;     -   Time 404;     -   Bluetooth indicator 405;     -   Battery status indicator 406;     -   Tray 408 with icons for frequently used applications, such as:         -   Phone 138, which may include an indicator 414 of the number             of missed calls or voicemail messages;         -   E-mail client 140, which may include an indicator 410 of the             number of unread e-mails;         -   Browser 147; and         -   Video and music player 152, also referred to as iPod             (trademark of Apple Inc.) module 152; and     -   Icons for other applications, such as:         -   IM 141;         -   Image management 144;         -   Camera 143;         -   Weather 149-1;         -   Stocks 149-2;         -   Workout support 142;         -   Calendar 148;         -   Alarm clock 149-4;         -   Map 154;         -   Notes 153;         -   Settings 412, which provides access to settings for device             100 and its various applications 136; and         -   Online video module 155, also referred to as YouTube             (trademark of Google Inc.) module 155.

FIG. 4B illustrates an exemplary user interface on a device (e.g., device 300, FIG. 3) with a touch-sensitive surface 451 (e.g., a tablet or touchpad 355, FIG. 3) that is separate from the display 450 (e.g., touch screen display 112). Although many of the examples which follow will be given with reference to inputs on touch screen display 112 (where the touch sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface that is separate from the display, as shown in FIG. 4B. In some embodiments the touch sensitive surface (e.g., 451 in FIG. 4B) has a primary axis (e.g., 452 in FIG. 4B) that corresponds to a primary axis (e.g., 453 in FIG. 4B) on the display (e.g., 450). In accordance with these embodiments, the device detects contacts (e.g., 460 and 462 in FIG. 4B) with the touch-sensitive surface 451 at locations that correspond to respective locations on the display (e.g., in FIG. 4B, 460 corresponds to 468 and 462 corresponds to 470). In this way, user inputs (e.g., contacts 460 and 462, and movements thereof) detected by the device on the touch-sensitive surface (e.g., 451 in FIG. 4B) are used by the device to manipulate the user interface on the display (e.g., 450 in FIG. 4B) of the multifunction device when the touch-sensitive surface is separate from the display. It should be understood that similar methods may be used for other user interfaces described herein.

Additionally, while the following examples are given primarily with reference to finger inputs (e.g., finger contacts, finger tap gestures, finger swipe gestures), it should be understood that, in some embodiments, one or more of the finger inputs are replaced with input from another input device (e.g., a mouse based input or stylus input). For example, a swipe gesture may be replaced with a mouse click (e.g., instead of a contact) followed by movement of the cursor along the path of the swipe (e.g., instead of movement of the contact). As another example, a tap gesture may be replaced with a mouse click while the cursor is located over the location of the tap gesture (e.g., instead of detection of the contact followed by ceasing to detect the contact). Similarly, when multiple user inputs are simultaneously detected, it should be understood that multiple computer mice may be used simultaneously, or a mouse and finger contacts may be used simultaneously.

User Interfaces and Associated Processes

Attention is now directed towards embodiments of user interfaces (“UI”) and associated processes that may be implemented on an electronic device with a display and a touch-sensitive surface, such as device 300 or portable multifunction device 100.

FIGS. 5A-5AD illustrate exemplary user interfaces for configuring restricted interaction with user interfaces and operating in a restricted interaction mode in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in FIGS. 6A-6E and FIG. 8.

FIGS. 5A-5P illustrate an exemplary user interface of an educational application in accordance with some embodiments.

FIG. 5A illustrates exemplary user interface 502 of the educational application. In FIG. 5A, user interface 502 is displayed on touch screen 112 of device 100. User interface 502 includes a plurality of user interface objects (e.g., the character “A,” the word “Apple,” a picture of an apple, and a plurality of menu bar user interface objects 504-1, 504-2, 504-3, 504-4, 504-5, 504-6, and 504-7, which, when activated, initiate respective operations. For example, user interface object 504-1, when activated (e.g., by a tap gesture), initiates replacing the displayed content (e.g., the character “A,” the word “Apple,” and the picture of an apple) with content from a previous page; user interface object 504-7, when activated (e.g., by a tap gesture), initiates replacing the displayed content with content from a next page; user interface object 504-2, when activated (e.g., by a tap gesture), initiates display of a list of documents or files configured for display in the respective application (e.g., the educational application); user interface object 504-3, when activated (e.g., by a tap gesture), initiates display of a help menu or help dialogue; user interface object 504-4, when activated (e.g., by a tap gesture), initiates display of a display properties menu; user interface object 504-5, when activated (e.g., by a tap gesture), initiates display of a bookmark menu; and user interface object 504-6, when activated (e.g., by a tap gesture), initiates display of a settings menu.

FIG. 5A also illustrates that touch gesture 503 is detected on touch screen 112. In response to detecting touch gesture 503, device 100 produces sounds corresponding to the pronunciation of the character “A” (e.g., device 100 plays an audio clip storing the pronunciation of the character “A”). FIG. 5A further illustrates that user input 505 is provided on home button 204 (e.g., home button 204 is pressed repeatedly three times in a row). An exemplary response displayed in response to user input 505 is illustrated in FIG. 5B.

FIG. 5B shows that, in some embodiments, exemplary password menu 506 is displayed over user interface 502 on touch screen 112 in response to user input 505 (FIG. 5A). A user may sequentially activate numerical buttons in password menu 506 (e.g., by tap gestures). When the user-provided sequence of numbers matches a preselected password, device 100 enters an interaction configuration mode, the user interface for which is illustrated in FIG. 5C. Alternatively, in some embodiments, in response to user input 505 (FIG. 5A), device 100 directly enters the interaction configuration mode without displaying password menu 506 (FIG. 5B).

FIG. 5C illustrates an exemplary user interface 501 of the interaction configuration mode, which includes user interface 502 displayed at a reduced scale. In other words, user interface 502 is displayed smaller in the interaction configuration mode (FIG. 5C) than in the unrestricted interaction mode illustrated in FIG. 5A. In some embodiments, the user interface 501 of the interaction configuration mode includes cancel user interface object 516, which, when activated (e.g., by a tap gesture), initiates exiting the interaction configuration mode and entering the unrestricted interaction mode. Once device 100 exits the interaction configuration mode, in some embodiments, the user interface shown in FIG. 5A is displayed. In some embodiments, the user interface 501 of the interaction configuration mode includes start user interface object 518, which, when activated (e.g., by a tap gesture), initiates exiting the interaction configuration mode and entering a restricted interaction mode, which is described below with respect to FIGS. 5M-5O, 5T, 5X, and 5Z.

In some embodiments, user interface 501 in FIG. 5C includes one or more of: touch interaction control user interface object 508, which, when selected, causes device 100 to ignore touch inputs on touch screen 112 while in the restricted interaction mode; rotate interaction control user interface object 510, which, when selected, causes device 100 to ignore rotation of device 100 while in the restricted interaction mode; shake interaction control user interface object 512, which, when selected, causes device 100 to ignore shaking of device 100 while in the restricted interaction mode; and motion interaction control user interface object 514, which, when selected, causes device 100 to ignore movement of device 100 while in the restricted interaction mode. As used herein, ignoring a particular input (e.g., a touch input, shaking of the device, movement of the device, etc.) means that the device does not respond to that particular input when the device is in the restricted interaction mode. In contrast, when in unrestricted interaction mode, device 100 responds to touch inputs on touch screen 112 (e.g., touch gesture 503, FIG. 5A), rotates the user interface from a portrait orientation to a landscape orientation or from the landscape orientation to the portrait orientation in response to detecting the rotation of device 100, performs a first predefined operation (e.g., an undo operation) in response to detecting shaking of device 100, and/or performs a second predefined operation (e.g., updating the user interface) in response to detecting movement of device 100. FIG. 5C illustrates that touch gesture 507 (e.g., a tap gesture) is detected at a location corresponding to touch interaction control user interface object 508, thereby selecting all touch interactions with the entire touch screen display for deactivation in the restricted interaction mode. An exemplary user interface displayed in response to touch gesture 507 is illustrated in FIG. 5D.

FIG. 5D illustrates that, in response to touch gesture 507 (FIG. 5C) at the location corresponding to touch interaction user interface object 508, touch interaction control user interface object 508 indicates that touch interaction on user interface 502 will be ignored while in the restricted interaction mode (e.g., note a line striking through touch interaction control user interface object 508). In addition, in response to touch gesture 507 at the location corresponding to touch interaction control user interface object 508 (FIG. 5C), the entire user interface 502 is visually distinguished (e.g., dimmed, shaded, displayed in a different color, marked with one or more indicators, etc.). A subsequent touch gesture (e.g., a tap gesture) at the location corresponding to touch interaction user interface object 508 removes the visual distinction of user interface 502, indicating that touch interaction on touch screen 112 will not be completely disabled while in the restricted interaction mode.

Similarly, in some embodiments, one or more of user interface objects 510, 512, and 514 indicate whether device 100 is configured to ignore (i.e., not respond to) the rotation, shaking, and/or movement of device 100 (e.g., by display of one or more lines striking through respective icons).

FIGS. 5E-5F illustrate that, instead of ignoring touch inputs on the entire user interface 502 by activating the touch interaction control user interface object 508, one or more separate user interface objects may be selected for deactivation.

In FIG. 5E, touch gesture 509 is detected at a location that corresponds to user interface object 504-2, thereby selecting user interface object 504-2 for deactivation while in the restricted interaction mode.

In some embodiments, as shown in FIG. 5AA, user interface objects that are configured to be selected by one or more gesture inputs are visually distinguished from other user interface objects that are not configured to be selected by gesture inputs in the interaction configuration mode. For example, the color(s) and/or outlines of the user interface objects that are configured to be selected by gesture inputs are changed in the interaction configuration mode to indicate that these user interface objects are configured to be selected by gesture inputs while the color(s) and/or outlines of the user interface objects that are not configured to be selected by gesture inputs remain the same (FIG. 5AA), or vice versa (not shown).

FIG. 5F illustrates that, in response to touch gesture 509 (FIG. 5E), user interface object 504-2 is visually distinguished (e.g., user interface object 504-2 is dimmed and/or indicator 528 is displayed over, or adjacent to, user interface object 504-2). In some embodiments, while device 100 is in the interaction configuration mode, one or more additional touch gestures are detected on touch screen 112 at respective locations corresponding to one or more other user interface objects, thereby selecting the one or more other user interface objects for deactivation while in the restricted interaction mode. In some embodiments, a subsequent touch gesture (e.g., a tap gesture) on user interface object 504-2 selects user interface object 504-2 for activation (i.e., deselects user interface object 504-2 for deactivation) and removes the visual distinction of user interface object 504-2. After device 100 enters the restricted interaction mode (e.g., in response to a tap gesture on the “Start” icon, user interface object 518), if user interface object 504-2 was selected for deactivation in the interaction configuration mode, device 100 ignores touch inputs at a location corresponding to user interface object 504-2 while in the restricted interaction mode.

In some embodiments, while device 100 is in the interaction configuration mode, multiple touch gestures (e.g., separate tap gestures or a collection of one or more tap gestures and/or one or more swipe gestures) are detected on touch screen 112 at respective locations corresponding to a plurality of user interface objects, thereby selecting the plurality of user interface objects for deactivation. After device 100 enters the restricted interaction mode (e.g., in response to a tap gesture on the “Start” icon, user interface object 518), if the plurality of user interface objects was selected for deactivation in the interaction configuration mode, device 100 ignores touch inputs at locations corresponding to the selected plurality of user interface objects while in the restricted interaction mode.

FIGS. 5G-5H illustrates an alternative method for selecting one or more user interface objects for deactivation while device 100 is in the interaction configuration mode. In FIG. 5G, touch gesture 511 is detected on touch screen 112. Touch gesture 511 moves across touch screen 112, while maintaining contact with touch screen 112, along a closed path (or nearly closed path) that resembles a rectangle.

FIG. 5H illustrates that device 100 recognizes the shape drawn by the movement of touch gesture 511 as a rectangle, and determines the size and location of the rectangle that corresponds to the path of touch gesture 511.

As shown in FIG. 5H, in some embodiments, rectangle 520, determined to correspond to the path of touch gesture 511, is displayed on touch screen 112. When rectangle 520 is displayed on touch screen 112, rectangle 520 is visually distinguished from the rest of user interface 502.

In some embodiments, deletion user interface object 564 is displayed over or adjacent to the shape corresponding to the path of touch gesture 511 (e.g., rectangle 520). In response to detecting a touch gesture at a location on touch screen 112 that corresponds to deletion user interface object 564, the shape corresponding to the path of touch gesture 511 ceases to be displayed (not shown).

In some embodiments, the shape corresponding to the path of touch gesture 511, such as rectangle 520, is moved in accordance with a touch gesture. For example, while rectangle 520 is displayed on touch screen 112, finger contact 561 may be detected at a location on touch screen 112 that corresponds to rectangle 520. While finger contact 561 is detected on touch screen 112, rectangle 520 moves in accordance with the movement of finger contact 561 (e.g., rectangle 520 moves with finger contact 561 on touch screen 112 until finger contact 561 ceases to be detected on touch screen 112). Alternatively, the movement of finger contacts 561 and 563 may be used to move rectangle 520 (e.g., the mid-point between finger contacts 561 and 563 determines the position of rectangle 520).

In some embodiments, the shape corresponding to the path of touch gesture 511, such as rectangle 520, is resized in accordance with a touch gesture. For example, the size of rectangle 520 is increased in response to a depinch gesture made by finger contacts 561 and 563 (e.g., finger contacts 561 and 563 moving further away from each other). Similarly, in some embodiments, the size of rectangle 520 is decreased in response to a pinch gesture made by finger contacts 561 and 563 (e.g., finger contacts 561 and 563 moving closer toward each other). In some embodiments, the pinch or depinch gesture resizes the shape without changing the aspect ratio of the shape. In some embodiments, a horizontal pinch or depinch gesture (e.g., finger contacts 561 and 563 moving horizontally relative to each other) changes the width of the shape without changing the height of the shape, thereby changing the aspect ratio of the shape. In some embodiments, a vertical pinch or depinch gesture (e.g., finger contacts 561 and 563 moving vertically relative to each other) changes the height of the shape without changing the width of the shape, thereby changing the aspect ratio of the shape. In some embodiments, a diagonal pinch or depinch (e.g., finger contacts 561 and 563 moving relative to each other with both horizontal and vertical components of movement) changes the width of the shape in accordance with the horizontal component of the diagonal pinch or depinch and the height of the shape in accordance with the vertical component of the diagonal pinch or depinch.

In some embodiments, the shape corresponding to the path of touch gesture 511, such as rectangle 520, is moved, rotated, and/or resized in accordance with a touch gesture (e.g., based on finger contacts 561 and 563).

Alternatively, the shape corresponding to the path of touch gesture 511 may be resized with a single finger gesture. In some embodiments, one or more resize handles 562 are displayed on touch screen 112 along one or more edges of the shape corresponding to the path of touch gesture 511 (e.g., rectangle 520). In response to detecting a finger contact on a respective resize handle and detecting the movement of the finger contact across on touch screen 112, the shape is resized.

In some embodiments, after device 100 enters the restricted interaction mode (e.g., in response to a tap gesture on user interface object 518), rectangle 520 is displayed and device 100 ignores touch inputs at a location corresponding to any user interface object located within rectangle 520 (e.g., the character “A”) while in the restricted interaction mode.

Alternatively, as shown in FIG. 5AB, in some embodiments, device 100 determines whether one or more user interface objects lie within the area outlined by a closed path (or nearly closed path) gesture, and visually distinguishes the one or more user interface objects that lie within the area outlined by the closed path (or nearly closed path) gesture. For example, in response to detecting gesture 511 (FIG. 5G), the device selects the letter “A” object within gesture 511 for deactivation and visually distinguishes the letter “A” object within gesture 511, as shown in FIG. 5AB. In some embodiments, when multiple user interface objects lie within the area outlined by the closed path (or nearly closed path) gesture, the multiple user interface objects are selected for deactivation and visually distinguished (not shown).

FIGS. 5I-5K illustrates another method for selecting one or more user interface objects for deactivation while device 100 is in the interaction configuration mode. In FIG. 5I, touch gesture 513 is detected on touch screen 112. Touch gesture 513 moves across touch screen 112, while maintaining contact with touch screen 112, along an open path, and the open path intersects (or comes into contact with) user interface objects 504-1 through 504-7, thereby selecting user interface objects 504-1 through 504-7. In some embodiments, one or more user interface objects located adjacent to the open path (e.g., within a predefined distance from the open path) are also selected for deactivation, even though they are not intersected by the open path.

FIG. 5J illustrates that user interface objects 504-1 through 504-7 are visually distinguished as a result of the selection by touch gesture 513 (FIG. 5I). After device 100 enters the restricted interaction mode (e.g., in response to a tap gesture on user interface object 518), if user interface objects 504-1 through 504-7 were selected for deactivation in the interaction configuration mode, device 100 ignores touch inputs at locations corresponding to any of user interface objects 504-1 through 504-7 while in the restricted interaction mode.

FIG. 5K illustrates an alternative user interface to that shown in FIG. 5J, where predefined shape 522 (e.g., a rectangle) enclosing the open path drawn by touch gesture 513 is visually distinguished. In some embodiments, predefined shape 522 and its size and location are selected so that predefined shape 522 includes all the user interface objects that are intersected by the open path of touch gesture 513 (FIG. 5I). After device 100 enters the restricted interaction mode (e.g., in response to a tap gesture on user interface object 518), predefined shape 522 is displayed and device 100 ignores touch inputs at locations corresponding to any user interface objects (e.g., user interface objects 504-1 through 504-7) located within predefined shape 522 while in the restricted interaction mode.

In FIG. 5L, touch gesture 515 (e.g., a tap gesture) is detected at a location that corresponds to user interface object 518, which causes the device to exit the interaction configuration mode and enter the restricted interaction mode. Two exemplary user interfaces 524 and 526, which may be displayed in response to detecting touch gesture 515 at the location that corresponds to user interface object 518 (FIG. 5L), are illustrated in FIGS. 5M and 5N, respectively.

In FIG. 5M, touch gesture 517 (e.g., a tap gesture) is detected in the restricted interaction mode at a location that corresponds to user interface object 504-3 located in predefined shape 522. In response to detecting touch gesture 517 at the location that corresponds to user interface object 504-3, device 100 ignores (i.e., does not respond to) touch gesture 517. FIG. 5M also illustrates that touch gesture 519 (e.g., a tap gesture) is detected in the restricted interaction mode at a location that corresponds to the character “A” displayed on touch screen 112. In response to detecting touch gesture 519 on touch screen 112 at the location that corresponds to the character “A,” device 100 produces sounds corresponding to the pronunciation of the character “A” because this part of the user interface was not selected for deactivation while in the interaction configuration mode.

Alternatively, in FIG. 5N, a plurality of user interface objects (e.g., the character “A,” the word “Apple,” and a picture of an apple) is displayed on touch screen 112, without displaying shape 522 and without displaying user interface objects 504-1 through 504-7 (FIG. 5L) located within predefined shape 522 (FIG. 5L). In FIG. 5N, the device does not respond to touch inputs in the area that corresponds to predefined shape 522 in FIG. 5L. In response to detecting a touch gesture (e.g., a tap gesture, not shown) on touch screen 112 at a location that corresponds to the character “A,” device 100 produces sounds corresponding to the pronunciation of the character “A” because this part of the user interface was not selected for deactivation while in the interaction configuration mode

FIG. 5N also illustrates detection of user input 521 (e.g., a triple click of home button 204).

FIG. 5O illustrates that, in some embodiments, in response to detecting user input 521 (FIG. 5N), password menu 506 is displayed over user interface 526. A user may sequentially activate numerical buttons in password menu 506 (e.g., by tap gestures). When the user-provided sequence of numbers matches a preselected password, device 100 exits the restricted interaction mode and enters the unrestricted interaction mode, the user interface for which is illustrated in FIG. 5P. Alternatively, in some embodiments, in response to user input 521 (FIG. 5N), device 100 directly exits the restricted interaction mode and enters the unrestricted interaction mode without displaying password menu 506. In some embodiments, the password for exiting the restricted interaction mode is identical to the password for entering the interaction configuration mode (FIG. 5B). Alternatively, the password for exiting the restricted interaction mode may be distinct from the password for entering the interaction configuration mode.

FIG. 5P illustrates user interface 502 after device 100 exits from the restricted interaction mode and enters the unrestricted interaction mode (e.g., in response to user input 521, FIG. 5N, and, if needed, entry of a matching password, FIG. 5O). As the name implies, in the unrestricted interaction mode, the user interface objects are configured to operate and respond without having some user interface objects disabled or otherwise prevented from being activated (which happens in the restricted interaction mode). For example, in FIG. 5P, touch gesture 523 (e.g., a tap gesture) is detected in the unrestricted interaction mode at a location that corresponds to user interface object 504-3. In response to detecting touch gesture 523 at the location that corresponds to user interface object 504-3, device 100 displays a help menu or help dialogue over user interface 502. FIG. 5P also illustrates that touch gesture 525 (e.g., a tap gesture) is detected in the unrestricted interaction mode at a location that corresponds to the character “A.” In response to detecting touch gesture 525 at the location that corresponds to the character “A,” device 100 produces sounds corresponding to the pronunciation of the character “A.” Object 504-3 and the character “A” respond normally to touch inputs in the unrestricted interaction mode.

FIGS. 5AC-5AD illustrate exemplary user interfaces for signaling an incoming call while in a restricted interaction mode in accordance with some embodiments.

In some embodiments, while device 100 is in the restricted interaction mode, an incoming call is declined unless predefined criteria are met. In some embodiments, while device 100 is in the restricted interaction mode, when device 100 receives an incoming call that satisfies predefined signaling criteria, device 100 outputs a signal indicating the incoming call. For example, in some embodiments, when an incoming call comes from a phone number in a predefined list of phone numbers (e.g., a phone number of a family member) or when multiple calls are received from a same phone number within a predefined time period (e.g., two or more calls received within one minute, two minutes, five minutes, etc.), device 100 outputs the signal indicating the incoming call. In some embodiments, the signal includes an audible signal (e.g., a ring tone). In some embodiments, the signal includes a visual signal. For example, device 100 may display a call application user interface, as shown in FIG. 5AC. Alternatively, as shown in FIG. 5AD, device 100 may display user interface objects 576, 578, and 580 over the currently displayed user interface to visually indicate the incoming call.

In some embodiments, when the device signals the incoming call, a user of the device still needs to perform additional inputs to answer the incoming call. In some embodiments, the user merely has to activate an “Answer” button 578 (FIG. 5AC or 5AD), e.g., with a tap gesture. In some embodiments, the user has to enter a password to exit the restricted interaction mode, as described above with respect to FIG. 5O. This would allow a parent or care giver to answer the phone, but prevent a child from answering the phone. In some embodiments, when the call ends, the device automatically returns to the restricted interaction mode.

In some other embodiments, device 100 exits from the restricted interaction mode (and/or enters the unrestricted interaction mode) in response to receiving an incoming call that satisfies the predefined signaling criteria while device 100 is in the restricted interaction mode.

FIGS. 5Q-5T illustrate exemplary user interfaces of a card matching game in accordance with some embodiments.

FIG. 5Q illustrates exemplary user interface 532 of the card matching game, which includes a plurality of user interface objects, such as “menu” and “exit” buttons, multiple cards, a user instruction message (e.g., “find the matching cards”), and a region for display of advertisement.

In FIG. 5Q, user input 531 (e.g., a triple click of home button 204) is detected.

FIG. 5R illustrates an exemplary user interface of the interaction configuration mode for the card matching game. In FIG. 5R, user interface 532 is displayed at a reduced scale. In other words, user interface 532 is displayed smaller in the interaction configuration mode (FIG. 5R) than in the unrestricted interaction mode (FIG. 5Q).

In FIG. 5R, gesture inputs 533, 535, 537, and 539 (e.g., tap gestures) are detected at locations that correspond to a plurality of user interface objects in user interface 532, thereby selecting the plurality of user interface objects.

FIG. 5S illustrates that the selected plurality of user interface objects is visually distinguished. FIG. 5S also illustrates that touch gesture 541 is detected at a location that corresponds to user interface object 518, a “Start” icon for exiting the interaction configuration mode and starting/entering the restricted interaction mode.

FIG. 5T illustrates exemplary user interface 534 displayed in response to detecting touch gesture 541 at the location that corresponds to user interface object 518. In FIG. 5T, user interface objects that are not selected by gesture inputs 533, 535, 537, and 539 (FIG. 5R) continue to be displayed on touch screen 112, and the rest of touch screen 112 is visually distinguished (e.g., dimmed, masked, covered, etc.). In some embodiments, device 100 displays, in response to touch gesture 541, only user interface objects that are not selected by gesture inputs 533, 535, 537, and 539 (FIG. 5R). In some embodiments, the user interface objects that are not selected by gesture inputs 533, 535, 537, and 539 (FIG. 5R) are rotated, centered, and/or resized to fill the display (not shown).

FIG. 5T also illustrates that touch gesture 543 (e.g., a tap gesture) is detected at a location corresponding to a user interface object that is not selected by gesture inputs 533, 535, 537, and 539 (e.g., a card in the card matching game). In response to detecting touch gesture 543 at the location corresponding to the user interface object that is not selected by gesture inputs 533, 535, 537, and 539, device 100 performs a predefined operation (e.g., displaying an animation of turning a card disposed at the location corresponding to touch gesture 543). FIG. 5T further illustrates that touch gesture 545 (e.g., a tap gesture) is detected at a location of a user interface object (e.g., the “menu” user interface object shown in FIG. 5Q, not shown in FIG. 5T) that is visually distinguished (e.g., masked). In response to detecting touch gesture 545 at the user interface object that is visually distinguished (e.g., masked), device 100 ignores (does not respond to) touch gesture 545.

FIGS. 5U-5X illustrate exemplary user interfaces of a musical instrument application (e.g., GarageBand by Apple, Inc.) in accordance with some embodiments.

FIG. 5U illustrates exemplary user interface 552 of the musical instrument application, which includes a plurality of user interface objects, such as guitar strings, an autoplay dial, a chords/notes switch, a guitar selection button, and multiple menu bar user interface objects.

In FIG. 5U, user input 551 (e.g., a triple click of home button 204) is detected.

FIG. 5V illustrates an exemplary user interface of the interaction configuration mode for the musical instrument application. In FIG. 5V, user interface 552 is displayed at a reduced scale. In other words, user interface 552 is displayed smaller in the interaction configuration mode (FIG. 5V) than in the unrestricted interaction mode shown in FIG. 5U.

FIG. 5V also illustrates that gesture input 553 is detected on touch screen 112. As illustrated in FIG. 5R, gesture input 553 includes dragging of a finger contact across touch screen 112, where the path of the finger contact intersects with a plurality of user interface objects.

FIG. 5W illustrates that predefined shape 556 that corresponds to gesture input 553 (FIG. 5V) is displayed in response to detecting gesture 553. In some embodiments, predefined shape 556, which is transparent (e.g., only border lines of predefined shape 556 are visible), semi-transparent, or opaque, is displayed on touch screen 112. FIG. 5W also illustrates that touch gesture 555 is detected at a location that corresponds to user interface object 518, a “Start” icon for exiting the interaction configuration mode and starting/entering the restricted interaction mode.

FIG. 5X illustrates exemplary user interface 554 displayed in response to detecting touch gesture 555 at the location that corresponds to user interface object 518 (FIG. 5W). In FIG. 5X, predefined shape 556 visually distinguishes user interface objects located within predefined shape 556 (e.g., by masking the user interface objects located within predefined shape 556 with semi-transparent predefined shape 556). FIG. 5X also illustrates that touch gesture 557 is detected at a location that corresponds to a guitar string user interface object. In response to detecting touch gesture 557 at the location that corresponds to the guitar string user interface object, device 100 plays a note that corresponds to the location of touch gesture 557 (e.g., device 100 plays a note that corresponds to the G chord). FIG. 5X further illustrates that touch gesture 559 (e.g., a tap gesture) is detected at a user interface object (e.g., the “my songs” user interface object) that is visually distinguished (e.g., masked). In response to detecting touch gesture 559 at the user interface object that is visually distinguished (e.g., masked), device 100 ignores (does not respond to) touch gesture 559.

FIGS. 5Y-5Z illustrate exemplary user interfaces of a folder in accordance with some embodiments. FIG. 5Y illustrates exemplary user interface 572 of the folder, which includes a plurality of user interface objects, such as file or application icons (e.g., alphabets, numbers, words, are counting), a list of directories (e.g., devices, untitled, untitled 1, etc.), and multiple menu bar user interface objects. User interface 572 may be configured for restricted interaction in a manner similar to configuration of the other user interfaces described above, which need not be repeated here.

FIG. 5Z illustrates exemplary user interface 574 of the folder in the restricted interaction mode, in accordance with some embodiments. In FIG. 5Z, file or application icons (e.g., alphabets, numbers, words, and counting) remain unchanged compared the corresponding icons in user interface 572 (FIG. 5Y), and the other user interface objects and the regions (e.g., the list of directories and menu bar user interface objects) are visually distinguished. A touch gesture (e.g., a tap gesture) at a location that corresponds to one of the file or application icons initiates execution of a corresponding application or opening of a corresponding file, whereas a touch gesture (e.g., a tap gesture) at a location that corresponds to the one or more visually distinguished regions is ignored.

FIGS. 6A-6E are flow diagrams illustrating method 600 of configuring restricted interaction with a user interface in accordance with some embodiments. Method 600 is performed at an electronic device (e.g., device 300, FIG. 3, or portable multifunction device 100, FIG. 1) with a display and a touch-sensitive surface. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 600 may be combined and/or the order of some operations may be changed.

As described below, method 600 provides an intuitive way to configure restricted interaction with a user interface for an electronic device. The method reduces the cognitive burden on a user when configuring restricted interaction with a user interface, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to configure restricted interaction with a user interface faster and more efficiently conserves power and increases the time between battery charges.

While in an unrestricted interaction mode, the device detects (602) a first input (e.g., detecting triple click 505 on home button 204 with or without subsequent entry of a passcode, FIGS. 5A-5B; pressing a particular combination of physical buttons; touching predefined regions of the touch-sensitive surface concurrently or in accordance with a predefined sequence; etc.).

In response to detecting the first input, the device enters (604) an interaction configuration mode that is distinct from the unrestricted interaction mode (e.g., FIG. 5C).

While in the interaction configuration mode, the device displays (606) on the display a first user interface that includes a plurality of user interface objects (e.g., user interface 501 in FIG. 5C includes the character “A,” the word “Apple,” a picture of an apple, and a plurality of menu bar user interface objects 504-1, 504-2, 504-3, 504-4, 504-5, 504-6, and 504-7 in user interface 502).

In some embodiments, the first user interface in the interaction configuration mode includes (608) a user interface displayed in the unrestricted interaction mode just prior to detecting the first input and the user interface displayed in the unrestricted interaction mode just prior to detecting the first input includes the plurality of user interface objects. For example, user interface 501 in FIG. 5C includes user interface 502 previously displayed in the unrestricted interaction mode (e.g., FIG. 5A) and user interface 502 includes the character “A,” the word “Apple,” a picture of an apple, and a plurality of menu bar user interface objects 504-1, 504-2, 504-3, 504-4, 504-5, 504-6, and 504-7.

In some embodiments, the user interface displayed in the unrestricted interaction mode just prior to detecting the first input is displayed (610) at a first scale in the unrestricted interaction mode (e.g., user interface 502 in FIG. 5A) and at a second scale, less than the first scale, in the first user interface in the interaction configuration mode (e.g., user interface 502 within user interface 501 in FIG. 5C). In some embodiments, the device displays an animation of the user interface displayed in the unrestricted interaction mode just prior to detecting the first input shrinking to become part of the first user interface in the interaction configuration mode.

In some embodiments, the first user interface is displayed (612) in response to detecting the first input. For example, in some embodiments, the user interface in FIG. 5C is displayed in response to user input 505 (FIG. 5A). For example, in some embodiments, the user interface in FIG. 5C is displayed in response to input of a password (FIG. 5B).

In some embodiments, the first user interface 501 displayed in the interaction configuration mode includes (614) at least one of: a touch interaction control user interface object (e.g., user interface object 508, FIG. 5C), which, when selected, causes the electronic device to ignore touch inputs on the touch-sensitive surface while in the restricted interaction mode; a rotate interaction control user interface object (e.g., user interface object 510, FIG. 5C), which, when selected, causes the electronic device to ignore rotation of the electronic device while in the restricted interaction mode; a shake interaction control user interface object (e.g., user interface object 512, FIG. 5C), which, when selected, causes the electronic device to ignore shaking of the electronic device while in the restricted interaction mode; and a motion interaction control user interface object (e.g., user interface object 514, FIG. 5C), which, when selected, causes the electronic device to ignore a movement of the electronic device while in the restricted interaction mode.

In some embodiments, while in the interaction configuration mode, the device determines (615, FIG. 6E) that one or more user interface objects, of the plurality of user interface objects, are configured to be selected by one or more gesture inputs and remaining one or more user interface objects, of the plurality of user interface objects, are not configured to be selected by one or more gesture inputs; and visually distinguishes the determined one or more user interface objects from the remaining one or more user interface objects. For example, as shown in FIG. 5AA, the user interface objects that are configured to be selected by one or more gesture inputs (e.g., user interface objects 504-1, 504-2, 504-3, 504-4, 504-5, 504-6, and 504-7, the character “A,” and the word “Apple,” but not the picture of the apple) are visually distinguished by having thick outlines. In some embodiments, the device determines that the one or more user interface objects are configured to be selected by one or more gesture inputs by determining that the one or more user interface objects are associated with one or more event recognizers 180 (FIG. 1B) and/or one or more event handlers 190 (FIG. 1B). In some embodiments, the one or more event recognizers 180 include one or more gesture recognizers 180 and/or the one or more event handlers 190 include one or more gesture handlers 190. For example, in some embodiments, when a respective user interface object is associated with a gesture recognizer and a gesture handler, the respective user interface object is deemed to be configured to be selected by one or more gesture inputs.

While displaying the first user interface, the device detects (616, FIG. 6B) one or more gesture inputs on the touch-sensitive surface (e.g., touch gesture 507, FIG. 5C; touch gesture 509, FIG. 5E; touch gesture 511, FIG. 5G; touch gesture 513, FIG. 5I; or touch gestures 533, 535, 537, and 539, FIG. 5R).

For a respective gesture input detected on the touch-sensitive surface, the device determines (618) whether one or more user interface objects of the plurality of user interface objects correspond to the respective gesture input. For example, in response to detecting touch gesture 507 (FIG. 5C) on user interface object 508, the device determines that the plurality of user interface objects in user interface 502 correspond to touch gesture 507. In FIGS. 5E-5F, in response to detecting touch gesture 509, the device determines that user interface object 504-2 corresponds to touch gesture 509. In FIGS. 5G-5H, in response to detecting touch gesture 511, the device determines that the character “A” corresponds to touch gesture 511. In FIGS. 5I-5K, in response to detecting touch gesture 513, the device determines that user interface objects 504-1 through 504-7 correspond to touch gesture 513. In FIGS. 5R-5S, in response to detecting touch gestures 533, 535, 537, and 539, the device determines a user interface object that corresponds to each of touch gestures 533, 535, 537, and 539.

In some embodiments, determining whether one or more user interface objects of the plurality of user interface objects correspond to the respective gesture input includes (620): determining a predefined shape from a plurality of predefined shapes, a size of the predefined shape, and a location of the predefined shape that correspond to the respective gesture input. In other words, the predefined shape corresponds to a shape drawn by the respective gesture input. Exemplary predefined shapes include rectangles, squares, circles, and ovals. In some embodiments, the predefined shape is overlaid on the first user interface. In some embodiments, additional gestures may be used to adjust the initial size and/or initial location of the predefined shape, such as depinch gestures to enlarge the predefined shape, dragging gestures on the border of the predefined shape to resize the predefined shape, and dragging gestures within the predefined shape to move the predefined shape. In some embodiments, the determining also includes determining whether the one or more user interface objects of the plurality of user interface objects correspond to the determined predefined shape with the determined size at the determined location. In other words, for a respective user interface object, the device determines whether the predefined shape that corresponds to a respective gesture input overlies the respective user interface object. For example, in FIG. 5H, the device determines that predefined shape 520 (which corresponds to touch gesture 511) overlies the character “A,” and selects the character “A” in accordance with the determination.

In some embodiments, the device visually distinguishes (621) the predefined shape. In some embodiments, the device visually distinguishes the predefined shape without visually distinguishing separately the one or more user interface objects that correspond to the determined predefined shape with the determined size at the determined location.

In some embodiments, the respective gesture input is (622) an open path gesture (e.g., a crossing-out or squiggly line, such as touch gesture 513, FIG. 5I and touch gesture 553, FIG. 5V). In some embodiments, the respective gesture input is a closed path gesture (e.g., touch gesture 511, FIG. 5G).

In some embodiments, the device identifies the first set of user interface objects in the plurality of user interface objects that correspond to the detected one or more gesture inputs and the second set of user interface objects in the plurality of user interface objects that do not correspond to the detected one or more gesture inputs. For example, in FIG. 5F, the device identifies user interface object 504-2 as a user interface object that corresponds to touch gesture 509 and the character “A,” the word “Apple,” the picture of an apple, and menu bar user interface objects 504-1, 504-3, 504-4, 504-5, 504-6, and 504-7 as user interface objects that do not correspond to touch gesture 509.

The device visually distinguishes (624) a first set of user interface objects in the plurality of user interface objects that correspond to the detected one or more gesture inputs from a second set of user interface objects in the plurality of user interface objects that do not correspond to the detected one or more gesture inputs. For example, in FIG. 5M, user interface objects 504-1 through 504-7 are visually distinguished from the other user interface objects in user interface 502, such as the character “A,” the word “Apple,” and the picture of an apple. In some embodiments, visually distinguishing the first set of user interface objects includes dimming display of the first set of user interface objects while maintaining undimmed display of the second set of user interface objects, and/or displaying one or more indicators (e.g., indicator 528, FIG. 5F) over, or adjacent to, the first set of user interface objects. In some embodiments, a respective user interface object in the first set of user interface objects is visually distinguished in response to detecting the respective gesture input that corresponds to the respective user interface object. In some embodiments, a respective indicator is a predefined shape displayed over, or adjacent to, one or more corresponding user interface objects in the first set of user interface objects. For example, in FIG. 5F, indicator 528 is displayed over user interface object 504-2. In some embodiments, a respective indicator is a free-form shape that corresponds to a respective gesture input, which is displayed over one or more corresponding user interface objects in the first set of user interface objects. In some embodiments, the opacity of a predefined or free-form shape may be adjusted in the interaction configuration mode.

The device detects (626) a second input (e.g., tap gesture 515 on start button 518, FIG. 5L).

In response to detecting the second input, the device exits (628, FIG. 6C) the interaction configuration mode and enters a restricted interaction mode that is distinct from the unrestricted interaction mode. In some embodiments, the restricted interaction mode prevents activation of (e.g., disables) user interface objects in the first set of user interface objects (e.g., user interface objects such as 504-1 through 504-7 in FIG. 5M), whereas these user interface objects in the first set of user interface objects are activatable in the unrestricted interaction mode (e.g., FIG. 5P).

In some embodiments, the user may use gesture inputs to select user interface objects to keep enabled rather than selecting user interface objects to be disabled. For these embodiments, the second set of user interface objects includes user interface objects in the plurality of user interface objects that correspond to the detected one or more gesture inputs, and the first set of user interface objects includes user interface objects in the plurality of user interface objects that do not correspond to the detected one or more gesture inputs.

In some embodiments, the device replaces (630) the first user interface with a second user interface that includes at least the second set of user interface objects in the restricted interaction mode. For example, in FIG. 5M, user interface 524 includes the second set of user interface objects (e.g., the character “A,” the word “Apple,” and the picture of an apple) as well as the first set of user interface objects (e.g., user interface objects 504-1 through 504-7 shown in FIG. 5L). In some embodiments, the second user interface does not include display of the first set of user interface objects. For example, in FIG. 5N, user interface 526 includes the second set of user interface objects (e.g., the character “A,” the word “Apple,” and the picture of an apple), but not the first set of user interface objects (e.g., user interface objects 504-1 through 504-7 shown in FIG. 5L). In some embodiments, the second user interface in the restricted interaction mode maintains the visual distinction, of the first set of user interface objects from the second set of user interface objects, that was created while in the interaction configuration mode. In some embodiments, the second user interface includes dimmed display of the first set of user interface objects while including non-dimmed display of the second set of user interface objects. In some embodiments, the second user interface includes highlighting of the second set of user interface objects. In some embodiments, the second user interface includes the second set of user interface objects rotated, centered, and/or fitted to a predefined display area of the display. In some embodiments, while in the restricted interaction mode: the device detects a first gesture on the touch-sensitive surface at a location that corresponds to a user interface object in the first set of user interface objects; and ignores the first gesture (e.g., touch gesture 517, FIG. 5M). In other words, while in the restricted interaction mode, the device does not respond to (or otherwise disregards) gestures on user interface objects that were selected for deactivation in the interaction configuration mode.

In some embodiments, the second user interface replaces (632) the first user interface in response to detecting the second input. For example, the user interface shown in FIG. 5L is replaced with user interface 524 (FIG. 5M) in response to detecting touch gesture 515 (FIG. 5L).

In some embodiments, while in the interaction configuration mode, the device ignores an activation of a respective physical button (e.g., push button 206 and/or volume adjustment buttons 208, FIG. 2). In some embodiments, while in the restricted interaction mode, the device ignores an activation of a respective physical button (e.g., push button 206 and/or volume adjustment buttons 208, FIG. 2).

In some embodiments, while in the restricted interaction mode: the device detects (634) a second gesture on the touch-sensitive surface at a location that corresponds to a user interface object in the second set of user interface objects; and, in response to detecting the second gesture, performs a predefined operation that corresponds to the user interface object in the second set of user interface objects. In some embodiments, the predefined operation that corresponds to the user interface object in the second set of user interface objects in the restricted interaction mode is the same as the predefined operation that corresponds to the user interface object in the second set of user interface objects in the unrestricted interaction mode. For example, in FIG. 5M, in response to touch gesture 519 on touch screen 112 at the location that corresponds to the character “A,” device 100 produces sounds corresponding to the pronunciation of the character “A.”

In some embodiments, while in the restricted interaction mode: the device detects (636) a predefined user input (e.g., user input 521, FIG. 5N, such as a triple click of home button 204); in response to detecting the predefined user input, displays a restricted interaction mode exit screen (e.g., password menu 506, FIG. 5O) on the display; while displaying the restricted interaction mode exit screen, detects one or more inputs (e.g., detecting one or more gestures on the touch-sensitive surface, such as tap gestures on the numeric buttons of password menu 506, FIG. 5O); determines whether the detected one or more inputs match a predefined input for exiting the restricted interaction mode (e.g., a predefined sequence of numbers); and, in accordance with a determination that the detected one or more inputs do not match the predefined input for exiting the restricted interaction mode, ceases to display the restricted interaction mode exit screen on the display (i.e., after a single entry of an incorrect password, password menu 506 disappears so that password menu 506 does not further distract the user). In some embodiments, after a failed attempt to exit the restricted interaction mode, the device will not display the restricted interaction mode exit screen for at least a predefined time period (e.g., one minute, two minutes, five minutes, etc).

In some embodiments, the device exits (638, FIG. 6D) the restricted interaction mode (e.g., in response to detecting triple click 521 on home button 204 followed by entry of a passcode, FIG. 5N; pressing a particular combination of physical buttons; touching predefined regions of the touch-sensitive surface concurrently or in accordance with a predefined sequence, such as touching four corners of the touch-sensitive surface in a predefined sequence; etc.). Thereafter, the device enters the unrestricted interaction mode; and, while in the unrestricted interaction mode: detects a third gesture (e.g., touch gesture 523, FIG. 5P) on the touch-sensitive surface at a location that corresponds to a first user interface object (e.g., user interface object 504-3, FIG. 5P) in the first set of user interface objects; in response to detecting the third gesture, performs a first predefined operation that corresponds to the first user interface object in the first set of user interface objects (e.g., a help menu or help dialogue is displayed over user interface 502 shown in FIG. 5P); detects a fourth gesture (e.g., touch gesture 525, FIG. 5P) on the touch-sensitive surface at a location that corresponds to a second user interface object (e.g., the character “A,” FIG. 5P) in the second set of user interface objects; and, in response to detecting the fourth gesture, performs a second predefined operation that corresponds to the second user interface object in the second set of user interface objects (e.g., the device produces sounds corresponding to the pronunciation of the character “A”).

In some embodiments, in response to detecting that the device has been plugged (e.g., external port 124, FIG. 2, of the device is plugged with a cable or into a cradle), the device exits the restricted interaction mode.

In some embodiments, immediately after exiting the restricted interaction mode, the device enters the interaction configuration mode (e.g., FIG. 5L) instead of entering the unrestricted interaction mode (e.g., FIG. 5P).

In some embodiments, information identifying the first set of user interface objects and the second set of user interface objects is stored (640) in an individual profile (e.g., individual profile(s) 159, FIG. 1A), where the individual profile is configured for a respective user. For example, a first preselected set of user interface objects for the educational application may be stored in an individual profile for a first user, and a second preselected set of user interface objects for the educational application may be stored in an individual profile for a second user. The first and second preselected sets of user interface objects may be used to facilitate rapid customization of the user interfaces for each individual user (e.g., based on the individual user's skills and needs). For example, all menu bar user interface objects (e.g., user interface objects 504-1 through 504-7, FIG. 5J) may be deactivated for the first user, while only a subset of the menu bar user interface objects (e.g., user interface objects 504-2 through 504-6, FIG. 5J) may be deactivated for the second user, thereby allowing the second user to perform additional functions (e.g., navigating to a previous or next page). In some embodiments, the device includes an individual profile for each application. For example the device may store a first individual profile for a respective user for a first application (e.g., the educational application), and a second individual profile for the respective user for a second application (e.g., the card matching game application).

In some embodiments, the device includes a call application. While in the restricted interaction mode in an application other than the call application, the device displays (642) a user interface for the application that includes at least the second set of user interface objects (e.g., a user interface in the restricted interaction mode, such as the user interface illustrated in FIG. 5N), receives an incoming call, and determines whether the incoming call satisfies predefined signaling criteria. The device, in accordance with a determination that the incoming call satisfies the predefined criteria, outputs a signal that indicates the incoming call (e.g., the device plays a ring tone and/or displays a user interface for the call application, such as the user interface shown in FIG. 5AC). The device, in accordance with a determination that the incoming call does not satisfy the predefined signaling criteria, foregoes outputting the signal that indicates the incoming call (e.g., the device does not play a ring tone or display the call application user interface).

In some embodiments, the predefined signaling criteria includes (644) that the incoming call is from a respective phone number in a predefined list of one or more phone numbers (e.g., a list of authorized phone numbers or callers, which is also called a “white list”).

In some embodiments, the predefined signaling criteria includes (646) that the incoming call is from a particular phone number, and a number of calls from the particular phone number during a predefined time period (e.g., one minute, two minute, five minutes, etc.) exceeds a predefined number of calls (two, three, four, five, etc.). For example, the predefined signaling criteria may require that calls be received from a same phone number at least three times during a two minute period.

In some embodiments, in accordance with the determination that the incoming call satisfies the predefined signaling criteria, the device displays (648) a user interface for the call application (e.g., the user interface illustrated in FIG. 5AC).

In some embodiments, in accordance with the determination that the incoming call satisfies the predefined signaling criteria, the device displays (650) a user interface that includes the plurality of user interface objects in the first user interface (e.g., the user interface objects displayed in the unrestricted interaction mode).

In some embodiments, the signal includes (652) an audible indication of the incoming call (e.g., a ring tone or a voice output indicating the incoming call).

In some embodiments, the signal includes (654) a visual indication of the incoming call (e.g., display of one or more user interface objects or display of the user interface for the call application).

In some embodiments, in accordance with a the determination that the incoming phone call does not satisfy the predefined signaling criteria, the device declines the incoming call and logs the incoming call as a missed call. In some embodiments, a number of missed call(s) is indicated as badge 414, as illustrated in FIG. 4A.

In some embodiments, information identifying the first set of user interface objects and the second set of user interface objects is stored in an individual profile (e.g., with storing unit 726), the individual profile configured for a respective user.

In some embodiments, the respective gesture input is an open path gesture.

In some embodiments, processing unit 706 is configured to, while in the restricted interaction mode in an application other than a call application, enable display of a user interface for the application that includes at least the second set of user interface objects (e.g., with display enabling unit 716, on display unit 702), receive an incoming call (e.g., with receiving unit 730), and determine whether the incoming call satisfies predefined signaling criteria (e.g., with determining unit 708).

FIG. 8 is a flow diagram illustrating method 800 of signaling an incoming call while in a restricted interaction mode in accordance with some embodiments. Method 800 is performed at an electronic device (e.g., device 300, FIG. 3, or portable multifunction device 100, FIG. 1) with a display, a touch-sensitive surface, and a call application. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on the display. In some embodiments, the display is separate from the touch-sensitive surface. Method 800 may be used for voice calls (e.g., via telephone module 138) and video calls (e.g., via video conference module 139, such as FaceTime® by Apple Inc. of Cupertino, Calif.). Some operations in method 800 may be combined and/or the order of some operations may be changed.

The electronic device, while in a restricted interaction mode, is typically configured by default to decline incoming calls and log these calls as missed calls, unless a call application is currently displayed. Other features that are typically disabled/restricted by default while the electronic device is in the restricted interaction mode may include:

-   -   Digital voice assistant (e.g., Siri by Apple Inc. of Cupertino,         Calif.);     -   Notification center;     -   Application switcher (e.g., multitasking gestures and/or button         activations for switching applications are ignored);     -   System wide gestures (e.g., an application exit gesture is         ignored);     -   Messages (e.g., SMS/MMS/iMessage messages are received but not         displayed, unless a messages application is currently         displayed);     -   Inputs from remote controls and/or headphone buttons; and     -   Alerts.

As a result, a user of the electronic device may miss important calls while the electronic device is in the restricted interaction mode.

As described below, method 800 provides an intuitive way to signal that there is an incoming call while the electronic device is in a restricted interaction mode. The method enables the electronic device to alert a user to incoming calls that meet predefined signaling criteria so that the user of the electronic device does not miss important calls.

While in a restricted interaction mode in an application other than the call application, the device displays (802) a first user interface for the application that includes a plurality of user interface objects (e.g., a user interface in the restricted interaction mode, such as the user interface illustrated in FIG. 5N).

The device receives (804) an incoming call, and determines (806) whether the incoming call satisfies predefined signaling criteria (e.g., whether the incoming call is from a phone number in a list of authorized phone numbers and/or whether the incoming call is from a particular phone number and a number of calls from the particular phone number during a predefined time period exceeds a predefined number of calls).

In accordance with a determination that the incoming call satisfies the predefined signaling criteria, the device outputs (808) a signal that indicates the incoming call (e.g., plays a ring tone and/or displays a user interface of the call application).

In some embodiments, the predefined signaling criteria include (810) that the incoming call is from a respective phone number in a predefined list of one or more phone numbers.

In some embodiments, the predefined signaling criteria includes (812) that the incoming call is from a particular phone number, and a number of calls from the particular phone number during a predefined time period exceeds a predefined number of calls.

In some embodiments, in accordance with the determination that the incoming call satisfies the predefined signaling criteria, the device displays (814) a user interface for the call application (e.g., the user interface illustrated in FIG. 5AC). In some embodiments, the user interface for the call application is overlaid on the first user interface for the application (e.g., FIG. 5AD). In some embodiments, the user interface for the call application replaces the first user interface for the application (e.g., FIG. 5AC).

In some embodiments, in accordance with the determination that the incoming call satisfies the predefined signaling criteria, the device displays (816) a second user interface that includes the plurality of user interface objects in the first user interface and one or more additional user interface objects not in the first user interface (e.g., one or more user interface objects for indicating the incoming call are overlaid over the first user interface for the application, as illustrated in FIG. 5AD).

In some embodiments, the signal includes (818) an audible indication of the incoming call.

In some embodiments, the signal includes (820) a visual indication of the incoming call.

In accordance with a determination that the incoming call does not satisfy the predefined signaling criteria, the device foregoes (822) outputting the signal that indicates the incoming call (e.g., the device does not output any signal that indicates the incoming call).

In some embodiments, in accordance with the determination that the incoming call does not satisfy the predefined signaling criteria, the device declines (824) the incoming call and logs the incoming call as a missed call.

It should be understood that the particular order in which the operations in FIG. 8 have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to method 600 (e.g., FIGS. 6A-6E) are also applicable in an analogous manner to method 800 described above with respect to FIG. 8. For example, the restricted interaction mode operations described above with reference to method 800 may have one or more of the characteristics of the restricted interaction mode entering operations described herein with reference to method 600. For brevity, these details are not repeated here.

In accordance with some embodiments, FIG. 9 shows a functional block diagram of electronic device 900 configured in accordance with the principles of the invention as described above. The functional blocks of the device may be implemented by hardware, software, or a combination of hardware and software to carry out the principles of the invention. It is understood by persons of skill in the art that the functional blocks described in FIG. 9 may be combined or separated into sub-blocks to implement the principles of the invention as described above. Therefore, the description herein may support any possible combination or separation or further definition of the functional blocks described herein.

As shown in FIG. 9, electronic device 900 includes display unit 902 configured to display, while in a restricted interaction mode in an application other than a call application, a first user interface that includes a plurality of user interface objects; call unit 904 configured to receive an incoming call; and processing unit 906 coupled to display unit 902 and call unit 904. In some embodiments, processing unit 906 includes display enabling unit 908, determining unit 910, outputting unit 912, foregoing unit 914, declining and logging unit 916.

Processing unit 906 is configured to: determine whether the incoming call satisfies predefined signaling criteria (e.g., with determining unit 910); in accordance with a determination that the incoming call satisfies the predefined signaling criteria, output a signal that indicates the incoming call (e.g., with outputting unit 912); and, in accordance with a determination that the incoming call does not satisfy the predefined signaling criteria, forego outputting the signal that indicates the incoming call (e.g., with foregoing unit 914).

In some embodiments, the predefined signaling criteria includes that the incoming call is from a respective phone number in a predefined list of one or more phone numbers.

In some embodiments, the predefined signaling criteria includes that the incoming call is from a particular phone number, and a number of calls from the particular phone number during a predefined time period exceeds a predefined number of calls.

In some embodiments, processing unit 906 is configured to, in accordance with the determination that the incoming call satisfies the predefined signaling criteria, enable display of a user interface for the call application (e.g., with display enabling unit 908, on display unit 902).

In some embodiments, processing unit 906 is configured to, in accordance with the determination that the incoming call satisfies the predefined signaling criteria, enable display of a second user interface that includes the plurality of user interface objects in the first user interface and one or more additional user interface objects not in the first user interface (e.g., with display enabling unit 908, on display unit 902).

In some embodiments, the signal includes an audible indication of the incoming call.

In some embodiments, the signal includes a visual indication of the incoming call.

In some embodiments, processing unit 906 is configured to, in accordance with the determination that the incoming call does not satisfy the predefined signaling criteria, decline the incoming call and log the incoming call as a missed call (e.g., with declining and logging unit 916).

The operations in the information processing methods described above may be implemented by running one or more functional modules in information processing apparatus such as general purpose processors or application specific chips. These modules, combinations of these modules, and/or their combination with general hardware (e.g., as described above with respect to FIGS. 1A and 3) are all included within the scope of protection of the invention.

The operations described above with reference to FIGS. 6A-6E and 8 may be implemented by components depicted in FIGS. 1A-1B. For example, detection operation 602, interaction configuration mode entering operation 604, and displaying operation 606 may be implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface (or whether rotation of the device) corresponds to a predefined event or sub-event, such as selection of an object on a user interface, or rotation of the device from one orientation to another. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 may utilize or call data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in FIGS. 1A-1B.
